Dota Allstars:
In the war of Humans and Orcs that occured long ago many Orcish warriors were corrupted by demonic influence and became tools of blackest darkness. One such warrior was the leader of the Half-Tribe of the Bloodied Axe Clan; Mogul Kahn. Mogul was slain by human Paladins but mysteriously was seen fighting alongside the Scourge around the time Mannoroth started to command the Orcs in the war against Archimonde. The Axe has been revived by demons and uses his reflexes and powerful blows to hunt down and seek out the Sentinels' agile warriors and cut them down to size, even projecting his lust for war onto them.

Dota 2:
As a grunt in the Army of Red Mist, Mogul Khan set his sights on the rank of Red Mist General. In battle after battle he proved his worth through gory deed. His rise through the ranks was helped by the fact that he never hesitated to decapitate a superior. Through the seven year Campaign of the Thousand Tarns, he distinguished himself in glorious carnage, his star of fame shining ever brighter, while the number of comrades in arms steadily dwindled. On the night of ultimate victory, Axe declared himself the new Red Mist General, and took on the ultimate title of 'Axe.' But his troops now numbered zero. Of course, many had died in battle, but a significant number had also fallen to Axe's blade. Needless to say, most soldiers now shun his leadership. But this matters not a whit to Axe, who knows that a one-man army is by far the best.
